Bridles and Bribery by Jo Grafford

To protect a woman and her unborn child, a small-town security firm goes head-to-head with an elusive criminal that most people don’t believe exists.

The law enforcement community calls him The Prophet since all he’s done so far is issue online threats. Like the cryptic ransom request Jillian Phillips receives for the child she’s still carrying — to be paid on her delivery date, no less. Either she’s the butt of a horrific prank, or she’s somehow landed in the crosshairs of a nameless, faceless enemy.
The police can’t do much since the crime technically hasn’t been committed yet. So, she turns to Lonestar Security for help, a company run by former bull riding champs. Only to discover her new husband is in the same criminal’s crosshairs.

A man who swept her to the altar only weeks after their first date. A man whose deadline from The Prophet has come and gone. And now he can’t be reached!
